My boyfriend does that sometimes when his mom is at home, eventhough I am quiet. I hate that. But if you were really annoying loud, than you deserved it. There was a time when I was really, really loud, because I thought he liked that, but it was actually very annoying if I think about it :'')

But when you orgasms, and you're alone, you may be as loud as you want. So FYL.
